IMPROVEMENT IN STEAM-BOlLiER-FLUE CLEANERS.

Specification forming part of Letters Patent No. 220,959, dated October '38, 1879; application filed May 26, 1879.

To all whom it may concern:

Be it known that we, BYRON B. BURTON and LEONARD LYNDE, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented new and useful Improvements in SteamBoiler-Flue Cleaners, of which the following is a description, reference being had to the accompanyin g drawings, making a part of this specification, in which- Figure 1 is an external side view of the cleaner. Fig. 2 is an end view. Fig. 3 is a transverse longitudinal section. Fig. 4 is a side view of the cone. Fig. 5 is an end view of the same.

Like letters of reference refer in the several views.

This invention is an injector for cleaning to like parts boiler-flues by the use of steam, which is injected into the fines from a circular opening in the head of the injector, whereby the steam is applied directly to the sides of the fines for removing the soot, &c., adhering to them.

The said injector consists of an external cylindrical-shaped shell, having fitted therein a coneshaped core, the outer end or head of which is a little less in diameter than the shell, so that between the shell and the core there is a narrow annular opening for the passage of steam also, within the shell is fitted a funnel-shaped lining, surrounding the inner end of the conical core above alluded to, and through which the steam passes to and around the core to the annular opening, thence into the fine.

The construction and operation of the invention will be more fully understood by thefollowing more complete description.

' As shown in the drawings, A represents the shell above alluded to. Said shell tapers from the shoulder a to the end b, to adapt it to different'sizeflues, into which it is inserted for injecting therein steam for cleaning them.

In the neck Bof the shell is cut a thread,

-into which is screwed the smaller end of the funnel-form lining O. The upper edge or rim of the lining is provided with an annular flange, D, projecting so far from the rim as to purpose of the said lining will presently be shown. 7

011 the inner side of the shell, above the lining, is cut a thread, into which is screwed the conical cone F, (detached views of which are shown in Figs. 4 and 5,) in which it will be seen that the core is provided with radial arms G, in the ends of which is cuta thread, where= by the core is screwed into the shell, as shown in Fig. 3.

It will be observed, on examination of the said Fig. 3, that the head H of the core does not touch the sides of the shell by which it is surrounded. A portion of the shell above the thread is chamfered 0E, thereby forming a narrow annular space or opening, 0, between the head of the core and the side of the shell, as seen in said Fig. 3.

The lower end or point of the core projects into the neck of the lining, around which is ample room for steam to pass around the core to the annular opening 0.

Into the outer end of the neck of the shell is screwed, a section of pipe, I, whereby the injector is handled by grasping the wooden shield J when in practical use.

As above said, this invention is for cleaning the flues of steam-boilers. To this end the injector, by means of the pipe I, is attached to the steam-boiler by a flexible tube. The head or shell A is then inserted in the end of the flue, and from the tapering form of the head it can be made to fit tightly therein.

The steam issuing from the boiler through the flexible tube and the pipe I passes through the injector, as indicated by the arrows, into the fiue. The steam therein causes a relaxation of the soot from the sides of the flue, and the impelling force of the steam drives it out of the opposite end.

The steam issues fr'om the injector in an annular form and close'to the side of the flue. Therefore it acts directly or endwise upon the incrustation of the flue, forcing it from the sides and out therefrom, thereby cleaning it.

The purpose of the lining O is to prevent the steam from spreading into the corners E of the shell, which, if permitted to do so, would to the flues. By allowing the steam to pass through the space I in nearly a direct line lts effect upon the flue is more forcible and effective in cleaning them.

The conical shape of the core divides the steam, causing an equal amount of pressure thereof on all sides of the core, so that its issue from the injector through the annular opening a will be equally efi'ective on all the inner surface of the flue.

In the event there should be any reaction of the steam, causing it to return around the shell, it is prevented from contact with the hand grasping the shield J by the shoulder a, which deflects the steam from the hand, and preventing it from being burned, thereby making the handling of the injector quite safe.
